The ISX12N meets ARB’s optional low NOx standard of 0.02 g/bhp-hr, a 90% reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr.

The Cummins Westport natural gas offering is the first Class 8 truck engine for larger heavy-duty vehicles to certify to the 0.02 g/bhp-hr optional standard and provides the trucking industry a near-zero emissions solution.

With production starting February 2018, the ISX12N natural gas engine will be available with ratings from 320hp to 400hp and up to 1,450 lbs.-ft. of torque. The engine is designed for line haul, regional haul, refuse, vocational trucks, motorcoach, and commuter buses.

All Cummins Westport engines offer the option of using compressed natural gas, liquefied natural gas, or renewable natural gas as a fuel source.

Everyone is talking about Tesla’s 250 truck orders while Cummins Westport is ramping up production and sales of NatGas engines in the 1000s. This is where the real green truck revolution is taking place. Tesla is a distraction.
